so, out of curiosity, did the Doctor went to christmas dinner with other of his companion's family?
was he in anyway involved in their lives? did he take them to visit dead/alternate relatives or their own past?

i haven't seen the old series so i wouldn't know, but these are just some of the things that, to me, mark the Doctor's attitude towards rose.

and well, there's the looks, the physical contact and all that.
cause i really don't think looks of utter adoration such as Ten on Christmas dinner showed up very often on old who.
